objective c - CGRectDivide with NULL pointer -


निम्नलिखित कोड में, nothing वेरिएबल से छुटकारा पाना संभव है? <पूर्व> सीजीआरटीईटीटटेबलविव्हीफ्रेम; सीजीआरटीएक्ट कुछ नहीं; सीजीआरटीएक्टिविइड (टेबलव्यूफ्रेम, और कुछ नहीं, और स्टार्टटालेव्यूफ्रेम, खोजब्लॉइट - सामग्रीऑफ़ेस्ट, सीजीआरटीएमईएज);

शून्य काम करने के लिए प्रतीत नहीं होता है कोई भी सुझाव?

धन्यवाद!

अच्छा, आप ऐसा कर सकते हैं <प्री> सीजीआरटीएक्टिवेट (टेबलव्यूफ्रेम, & amp; (सीजीआरएक्ट) {}, और स्टार्टटायबल वीफ्रेम, खोजबार हाइट - कंटेंटऑफ़सेट, सीजीआरटीएमआईएजेड);

या यहां तक ​​कि: 

  माइक्रैक्ट डिवाइड (सीजीआरटी आर, सीजीआरएक्ट * टुकड़ा, सीजीआरएक्ट * शेष, सीजीफ्लॉट डी, सीजीआरएक्टएजेज एज) {स्लाइस = स्लाइस? टुकड़ा: & amp; (सीजीआरटीएक्ट) {}; शेष = शेष? शेष: & amp; (सीजीआरटीएक्ट) {}; सीजीआरसीटीडीवाइड (आर, टुकड़ा, शेष, डी, किनारे); }

mongodb - CakePHP paginator ignoring order, but only for certain values -
